In said drawings: a 7 Figure 1 is an upper plan view of a complete drying or disinfecting plant applied to w a silo for storing corn in cobs.

' The reference letter a-indicates a series of openings provided in the distributing duct and b are suit-able flanges for supporting .th protecting fabric or gauze 3. V The manner of operating accordance withlour invention, is as follows: When it is desired, for instance, to dry the contents of a corn .silo or the like,the stove I is charged with a suitable amount of glowing charcoal and feeding of such fuel is continued during the time and in the propor reference have been the device in n n "were: 83 92$- a: fioli "f l i by i P r lar? deal-cent eeei se 're ma l moisture-of the grain. or other product to be f hot'or coldairor of disinfecting or curing s Thereupon, theventilator'is'started 'so 'as to draw the. hot air through "tlie'filter of I i the stove,indicatediiiSl-fand the suction pipe V i 5, whereupon said air,- after passingthrough 1 the ventilator is led by means ofthefee'd I duct6 to the distribution pipe 8, whence it silo together with the hot air .7

Vhen'it is desired to simply ventilateor I For driving the ventilator, any suitable.

source of power may beused, suchas obtained by applying'a pulleytothe drive wheel of a motor car, or 1n any"other convenient or known manner; it will, also ,be I evident that the ventilator may be driven by f hand, if desired, and inflc'ase of small amounts of corn or the likefihavingto' be] submitted to a short treatment.

The experiments which we on, showed that, in asilo containingcorn cobs of, say 17.30% of moisturefafter treat; ingthesame with the apparatusabove de scribed and using the motive power derived from the wheel of anordinary, small motor car,'said contents of moisture were'readily and speedily reduced to l t/70% v at a'small cost'of labor and fuel,"
